SymbolTable()

Default constructor

~SymbolTable()

Destructor

SymInsertStatus AddSymbol(SymbolObject* )

Adds a symbol to the current scope of the table.

bool GetSymbol(const String* , SymbolObject* &, long &, bool = 0)

Retrieves a pointer to a symbol from the symbol table. The symbol returned is the one identified by the first parameter. The symbol table is searched for the relevant symbol from the current scope, down to the base scope. If the symbol is found, a copy of the pointer, and the level where the symbol was found are returned as the second and third parameters (respectively), and a value of "true" is returned. Note: Do not deallocate the pointer returned, as it is a copy of the stored memory. Deleting it will cause a segmentation fault.

bool NewScope()

Adds a new level to the stack. Symbols added will be added to this level.

bool DeleteScope()

Removes the current level from the stack. All symbols on the current level of the stack will be seleted.

long GetCurrentScopeLevel()

Obtains the level number of the current scope
